Monarch butterflies are in serious danger
TOTAL MONARCH BUTTERFLY NUMBERS HAVE BEEN REDUCED BY A BILLION BUTTERFLIES
Brower said in order to bring the monarch population up to a safe number, more than a billion milkweeds need to be planted. There are various groups involved with the effort to help the monarch population, including Monarch Joint Venture, which is a partnership of federal and state agencies, non-governmental organizations and academic programs working together to support and coordinate efforts to protect the monarch migration across the lower 48 states.
We need to preserve the places monarchs need to live
california used to play a large role in migration as well where they go and stay by the ocean over winter but so many have been wiped out, not many left. Want to bring them back again for all of us to enjoy!
PESTICIDES ARE THE ROOT CAUSE OF THE BUTTERFLY
AND BEE COLONY DISAPPEARANCE
Friends of the Earth research found that 51% of plants sold to consumers at a range of garden centres across the United States and Canada were contaminated with neonics–
The high percentage of contaminated plants…and their neonicotinoid concentrations suggest that this problem is widespread, and that many home gardens have likely become a source of exposure for bees. The results indicate that neonicotinoids occur in both flowers and in stems and leaves, with some samples having higher concentrations in flowers than greenery and other samples showing the reverse.
Nurseries commonly apply systemic pesticides as soil injections, granular or liquid soil treatments, foliar sprays (applied to leaves), and seed treatments. Water-soluble pesticides are readily absorbed by plant roots and transported systemically in the plant’s vascular system to other portions of the plant, including roots, pollen and nectar, leaves, stems, and fruit.This systemic action results in the exposure of beneficial, non-target insects such as bees to potentially lethal doses of these pesticides.
This human health risk assessment for imidacloprid was conducted because adverse effects on the liver and the thyroid gland were observed following subchronic and chronic exposures. This Risk Characterization Document (RCD) evaluated the potential health hazard from exposure to imidacloprid residues in the food and drinking water. The exposures from ambient air, occupational activities and residential uses of imidacloprid, as well as aggregate exposures from various combined scenarios, will be subsequently evaluated in an addendum to this RCD. The toxicological profile was based on studies on file at the DPR, which were submitted for fulfilling the pesticide registration data requirements under the California Birth Defect Prevention Act of 1984 (SB 950). Published experimental data were also used to characterize the imidacloprid toxicity. Relevant publications were searched from the electronic databases at the National Center for Biotechnology Information (NCBI, http://www.ncbi.nlm.nih.gov/entrez/query.fcgi; http://toxnet.nlm.nih.gov/). The most recent database search was conducted in November 2004, and the document was updated accordingly.
